To all whom it may concern:

Be it known that'we, GEORGE OLEMEN'rs and learns M. HosrLER, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and usefullmprovements in Heat Controlling Apparatus, of which the following is a specification.

Our invention has relation to heat-controlling apparatus; and it consists in the construction and arrangement of parts, as will be hereinafter described and particularly claimed.

Figure 1 is a side elevation of one half of a radiator, illustrating the application of the valve to the feed-p1 e. Fig. 2 is a central longitudinal sectiona viewof the valve-casing containing the mechanism for regulating and controlling the feed to the radiator. Fi 3 is a view similar to Fig. 1 of the other haf of the radiator, illustratin the application of the valve to the pipe ad Fig. 4 is a central longitudinal section of this form of valve. I

Referrin to the drawings by reference-numerals, 1 esignates a radiator of-common construction, 2 a feed-pipe, and 3 the returnpipe, both of which are adapted to be connected to the radiator in any suitable manner. Inter osed in said ipes at points adj acent the ra iator are va ve-casin s 4 and 5, which contain the mechanism or seating and unseatin the valves which control the feed and disc arge of the condensation, res ectively. The valve-casings are substan tially duplicates in constructlon, and each is provided with an inlet 6 and an outlet 7, and arranged adjacent to the outlet of the casing 4 and the inlet of the casing 5 are valve-seats 8. Arms 9 are pivotally secured within the easmg 5 and have suitably connected thereto va ves 10, which are ada ted to be automatically seated and unseate The valve-casings have their upper ends open to permit of access being gained to their interiors, said opening's being closed by removable ca s 11. The casing 4 1s rovided at a point a jacent its outlet and t e casing 5 is provided at a point adjacent its inlet with threaded openin s adapted to receive externally and internal y threaded sleeves 12, the inner ends thereof.

being adapted to project within the casings. Expanslble members 13 are mounted within the casings and are so connected and associated with the valves that their expansion or apted to convey the condensation away from the radiator.

contraction will either close or open said valves. The members are hollow and approximately U-shaped, each having oneof 1ts ends rigidly connected to the casing in such a manner that its other, free, end is ada ted,

during the ex ansion or contraction o the member, to re atively move toward and from an adjusting-screw, hereinafter referred to. The members have their fixed ends open, said fixed ends being secured to the inwardly-projecting portions of the sleeves 12, while the free ends are provided with rojections 13, adapted to be received by s otted lugs 13*, formed upon the lower ends of the arms 9.

vIt is apparent in view of the eculiar construction of the members thatw on they contract their free ends are adapted to move away from the valve-seat in acute planes with relation to the longitudinal centers of said valve-seats, which movement, through virtue of the connection between the arms and said free ends,will cause the valves to be unseated or opened. The expansion of the members will cause the free ends to move reversely, and consequently seat or close the valves. The projections 13 are adapted to have a slight movement in the slots of the lugs 13 to compensate for the peculiar movement of the free ends of the members 13 when said members either contract or expand.

A pipe 14 has its lower end secured to the sleeve 12 of the casing 4 and its upper end suitably connected to a thermostat (not shown) which is adapted to regulate a flow of compressed air which is conveyed by the ipe 14 to the member 13. When the atlnosp ere within the room risesto a certain temperature, the thermostat operates to permit the com ressed air to flow into the member 13, whic causes the latter to expand and seat or close the valve, whereby the flow of the fluid to the heating a paratus is cut oii. When the temperature i a ls, the thermostat will operate to cut ofi the flow of compressed air and permit the escape of that remaining in the pipq14 and member 13, which permits the member to contract of its own adherent nature and unseat or open the valve to permit within thecasin'g 5, is adapted to be caused by any suitable expansible fiuid mounted will become cooled, which cooling will cause the fluid in the member 13 to contract, and thereby permit the member to contract, and as the contraction of the member will unseat the valve said condensation will be i'reeto flow ofi"; ;As soon as a suflioient quantity of the cooled condensation has passed off to brin the heated condensation or that in close relation to the steam the interior of said casing will become heated, and thereby cause the fluid within the member 13 to expand, which expansion will also cause the expansion of the member and seat the valve.

It is apparent from the above description, taken in connection with the accompanying drawings, that we provide a valve which may regulate the flow and discharge of a heating Y fluid to an apparatus in such a manner that 'a room may befkept at an even te eratu're.

Plu s 18 are movabl mount I within the rear 0 the'casings an have their ends projectin therewith. The plugs are provlded with t eaded recesses adapted to receive threaded bolts 19, which are adapted to lie in the path of the members 13, so as to be eng'a ed by the latterto limit their expansion. he

bolts are adapted to be moved outwardly and inwardly to regulate the degree of expansion of the members to ermit the valves to be moved away from t e seats at various distances.

Havin thus fully described the invention, what is c aimed as new is- 1. A valve-casing, an arm within and pivoted to the casing adjacent to the valve-seat, said arm carrying intermediate its ends a valve, a hollow member connected at one end to the va1ve casing and at its other end loosely connected to the free end of the arm, said member adapted under variations of internal pressure to operate the arm, and thus the valve.

2. A valve-casing, an arm within and pivoted to the casing adjacent to the valve-seat,

said arm carrying intermediate its ends a valve, a hollow member connected at one end to the valve casing and at its other end loosely connected to the free end of the arm, said member ada tedto ex and under internal pressure to c ose the va ve, and contract of its own inherent nature toopen the valve when said pressure-is removed.

In testimony whereof we afiix our signatures in presence of two witnesses.
